    • The invention is to realize a gas ejection mechanism, which makes it possible to form a uniform gas flow and to control the temperature and its distribution over a gas plate, and thereby to provide a surface processing apparatus which can continuously carry out uniform processing. A surface processing apparatus of this invention comprises: a process chamber in which a substrate holding mechanism and a gas ejection mechanism are arranged to face each other; an exhaust means; and a gas supply means; wherein a gas distribution mechanism, a cooling or the heating mechanism provided with a coolant channel or a heater to cool or heat a gas plate and a number of gas passages, and the gas plate having a number of gas outlets communicated with the gas passages are arranged in that order from the upper stream to construct the gas ejection mechanism, and wherein the gas plate is fixed to the cooling or heating mechanism with a clamping member or with an electrostatic chucking mechanism. A second gas distribution mechanism may be installed between the gas plate and the cooling or heating mechanism so as to form gas outlets under the coolant channel.
    • 本发明是为了实现气体喷射机构,其能够形成均匀的气流并且控制温度及其在气板上的分布,从而提供能够连续进行均匀处理的表面处理装置。 本发明的表面处理装置包括:处理室,其中基板保持机构和气体喷射机构彼此相对配置; 排气装置; 和气体供给装置; 其特征在于,具有冷却通道的冷却或加热机构,或用于冷却或加热气板和多个气体通道的加热机构以及具有与气体通路连通的多个气体出口的气体板的气体分配机构, 从上游按顺序排列构成气体排出机构,其中,气板用夹紧构件或静电吸附机构固定在冷却或加热机构上。 第二气体分配机构可以安装在气体板和冷却或加热机构之间,以在冷却剂通道下形成气体出口。
